Synthesis of hollow CdS micro-/nanospheres by CoSP technique and their visible light photocatalytic activities

The CdS hollow micro-/nanospheres with nanomorphology have been successfully synthesized by a continuous spray pyrolysis technique. The experimental conditions mainly the temperature and the nature of solvent are found to influence the creation of hollow spheres. The product prepared by this technique shows high photodegradation efficiency (∼90%) of methylene blue dye under visible light.
